Why it matters
Property tax is based on the county's value. A home valued too high pays too much tax every year, and the owner can ask for a lower value. Agents and appeal consultants help owners do this.
Where it shows up in public records
The county's market value for the home, compared with recent arm's-length sales of similar homes, and with the county's own average value for the neighbourhood. A home appears only when both tests agree.
How to use it
- Agents: it is a helpful reason to call a homeowner, with a real number.
- Mention the filing window: a late appeal usually has to wait a year.
- Use the one-page appeal letter in the app; the owner files the appeal.
